This fallen prey : a Rockton novel
(Book)

When Casey first arrived at the off-the-grid town, an isolated community built as a haven for people running from their pasts, she had no idea what to expect, with no cell phones, no internet, no mail, and no way of getting in or out without the town council's approval. She certainly didn't expect to be the homicide detective on two separate cases or to begin a romantic relationship with her boss.
